Why teams connect Intercom and Smartsheet
Sync what happens in Smartsheet with the customer records in Intercom, in real time and in both directions.
The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Smartsheet holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.
Stacksync connects Cells, Reports, Attachments, Discussions and Comments in Smartsheet to Contacts, Companies, Conversations, Tickets in Intercom with bi-directional, real-time sync. Activity and record changes in Smartsheet update the matching contact or account in Intercom, and CRM data flows the other way wherever Smartsheet can store and use it.
Common use cases
- 01 Write records from a CRM or ERP into Smartsheet Rows so ops teams manage intake and status in a grid, then push status Cells back to the source.
- 02 Pull Reports and Sheets into a warehouse for cross-project reporting and dashboards without manual CSV exports.
- 03 Sync contacts and companies bi-directionally with the CRM so support sees deal context and sales sees conversation history
- 04 Push product usage events from an application database into Intercom to trigger onboarding and retention messages
Common sync patterns
Where Smartsheet can store CRM context: fields kept current
Owner, lifecycle stage, or account details from Intercom sync into Smartsheet, so people working there have the context without switching tools.
Where Smartsheet supplies contact or company data
Enriched fields land directly on records in Intercom, and refreshes keep them from going stale.
What you can sync between Intercom and Smartsheet
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Intercom objects | Smartsheet objects | How this pairing syncs | |
|---|---|---|---|
| Segments Saved audience definitions are readable for targeting parity across tools. | Users and Groups Account membership and sharing; synced to keep an HR or identity source aligned with sheet and workspace access. | Segments is specific to Intercom and Users and Groups to Smartsheet — each maps to any object or custom field on the other side. | |
| Admins & Teams Teammate records map conversation ownership to CRM users. | Sheets The core container; each sheet has typed columns, rows, and a modifiedAt stamp. Stacksync treats a sheet as a table and syncs its rows two-way. | Admins & Teams is specific to Intercom and Sheets to Smartsheet — each maps to any object or custom field on the other side. | |
| Articles Help center content is accessible via API for knowledge sync and audits. | Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. | Articles is specific to Intercom and Rows to Smartsheet — each maps to any object or custom field on the other side. | |
| Contacts A single contact model covers both users and leads, distinguished by a role attribute. | Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. | Contacts is specific to Intercom and Columns to Smartsheet — each maps to any object or custom field on the other side. | |
| Companies Company records group contacts and carry plan and account attributes used in segmentation. | Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. | Companies is specific to Intercom and Cells to Smartsheet — each maps to any object or custom field on the other side. | |
| Conversations Support and sales threads sync outward for analytics and CRM context. | Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. | Conversations is specific to Intercom and Reports to Smartsheet — each maps to any object or custom field on the other side. |
How changes propagate between Intercom and Smartsheet
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Intercom Smartsheet Sub-second propagation
DetectionIntercom notifies Stacksync of record changes through webhook events. Webhook topic subscriptions for contact, company, and conversation events, plus polling for backfill.
DeliveryEach detected change is written to Smartsheet through its API, with automatic retries and rate-limit backoff.
Smartsheet Intercom Sub-second propagation
DetectionSmartsheet notifies Stacksync of record changes through webhook events. Sheet-scoped webhooks subscribed to *.* events notify on row and cell changes.
DeliveryEach detected change is written to Intercom through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Intercom: Subject to per-app rate limits on the Intercom API.
- Smartsheet: 300 requests per minute per access token; heavy calls like posting attachments cost 10x (30/min). A 429 returns errorCode 4003, back off ~60s.
